LLI H. AWHORN; or DALLAS, TEXAS.' I i DOUBLE-SERVICE ENVELOPE am) srArIoNERYcom INnn Application filed July 7, 1926. sen-aw... 120,912.

My invention relates to envelopes and more particularly to double service envelopes and doubleservice stationery; and the objectis to provide in a single piece of paper an origianl sheet for a letter, an order blank for return, a blanksheet for an answer or return letter, an original sealingstrip, a return sealing flap, and; as many sheets for manifolding as may be desirable or necessary. Another advantage is the means for closing the folds so that the contents of a letter or order cannot bereadwithout unsealing the envelope. Another object is to provide stationery for keeping duplicate records of all correspondence more economn cally. Other objects and advantages will be fully explained'in the following description and the invention will be 'more particularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of this appli cation.

Fig. 11 is. an enlarged view.showingtl1e entire envelope and letter just as cut from a sheet of paper. A

. Fig. '12 is the reverse side of Fig. '11.

Similar characters of reference are used to indicate the same parts throughout the several views.

In the drawings the body 1 is fora letter or an order or any other suitable matteron 5 the inside and the address on the outside2.

The envelope is provided with a seal flap 3' for: forwarding first-class matter, and it has i a flap 4; which serves asa seal for the return of firstsclassmatterand the same flap can be used for kt-he return address. The envelopefhas a window 5 which serves when 7 second-class matter is being forwarded to render visible,instructions to withdraw the flap/tfor unfolding or openingof the en} velope. To forwardsecond-class matter,

run the flap 4 down inside of the body 1 as shown in'Fig. 10, this flap bearing instructionssuch as Pull flap here as shown in Fig. 12. p p I When there is advertising to be done, the

lateral flaps 6 and 7 may be used on one face f for this purposega'ndthe other faces may be used for first-class matter or for a return letter or similar letter.

Extensions 8, as many as may be desired,

can be used and theseextensions are foldable inwardly and may be used for letters on one side either going or coming in and the address onthe other side or advertising matter. Carbon sheets with second sheets may be used when copies are wanted. .The

flap twill lock the carbon and second sheets in position to prevent slipping when being manipulated by the operatorg" I Seal flaps 9 may be used at the ends of the envelope to seal the envelope to prevent unauthorized persons from reading any of the contents of the letter, and thesefiaps 9 need a r not be gummed because they lock automatically by reason of 'the'fold.' The paper may be slitted along the dotted outline. L

In operation, the letter or order is Written on the faceof plate 1 and the address on. p

the outsidefQ. The flaps 6, 7 and; 8 can then be folded: on the body 1. I The messages may be written on either sideof the sheet and folded inwardly- The letter or order orboth can be folded inwardly, and thensealed with a the side sealing flap 3 which may be gummed.

Ifonly second-classmatter is to be sent, the

fia l may be used to lock the device closed as in Fig. 10. .lVh'en the device has first-class matter the seal 3 must be broken before the I envelope canbe opened. When the device is to bereturned with first-class matter it is" sealed with the'fiap 4 by gum or otherwise as shown in F ig.;5 for the return. The fflaps 9 are used to sealthe end to prevent unauthorize'd persons from reading'the contents of the letter. Either end maybe sealed with the g The stationery sheets can be prepared, as

velope;flsaid lettersheets being arranged to i I shown in Figs. 11 and 12 With printed matter or other indices for return address and any other suitable or useful instructions niay be printed on thestationery. 7 The devicemay be provided with a thread or cord 11 attached thereto Ior unsealing'the letter by cutting the seal 3 with thejcord or thread.
